We are told it is now "not looking likely" that Lambert will join the "Idol" judging panel, despite previous plans to bring Idol alums to the table. (Those plans are being reconsidered thanks to a change in leadership behind the scenes, including the departure of Fox reality boss Mike Darnell and show producer Nigel Lythgoe.)

Fox recently confirmed that four cast members would not be returning as series regulars this fall: Heather Morris, Amber Riley, Mark Salling and Harry Shum, Jr.

Jayma Mays also has nabbed a role on another network, starring opposite Will Arnett on CBS' "The Millers."
